The F-22 has improved high-altitude performance because of a number of factors. Engine airflow, intake design & wing loading. Some reports have the pilots using the afterburners above 50,000 (alt Restrictions not withstanding) but other reports say that once at altitude, the F-22 will supercruise quite fast at 60,000. The F-22 has significantly less drag on the airframe, compared to other jets like the F-15.
